This application is adivision of applicants .copending'application for United States Let- ;ters Patent S. N37 0,280, filedJune 12, 1929, for dispensing equipment.

Vending machine 1 has article discharging mechanism 2. for delivering a series of articles 3, one by one, to opening 4 of thevending machine 1. A suitable mechanism 2'is shown herein as comprising endless chain 5 having pawl 6 for successively engaging pins 7 to release shelves 8so that such may swing downward from their respective fulcrums 9 to allow the article 3 to drop to the bottom of the machine 1, in a position accessible for withdrawal by one making the purchase.

Mechanism 10 is supplied to rotate disk 11 carrying notations 12 for indicating through window 13 the residual charge invthe magazine. The movement of the chain 5 herein is effected by gear 14 mounted on shaft 15.

The invention herein relates more particularly to the coin control mechanism for imparting rotation to the shaft 15 and from this shaft 1'5 any suitable vending mechanism 7 may be controlled.

The vending equipment 1 is provided with opening 16 in one side thereof through which checks or coins may be inserted into disk 17 having seats 18, 1'9, 20. In the instance wherein three coins of two di-fierent denomi- J radially outward thereby to clear the tooth 1930. Serial No. 464,806.

nations are used, as herein, the smaller piece, such as a- 10 silver coin may be placed in the seat 18, while two larger coins as 193 copper pieces may be placed in the seats 19, 20. With the checks or coins thus introduced, crank 21 maybe operated clockwise and beingkeyed to shaft 22 rotates the shaft and consequently rotates the disk 17 with which the shaft 22 is an integral part. The disk 17 carries inwards ly extending pin 23 to ride in slot 24 of come0 panion disk 25 adjacent the disk 17 In this movement of the disk 17 there is resistance of spring 26 having end 27 anchored with the disk 25 and the opposite end engaged by pin 28 fast with the disk 17. This are of clockwise movement of the crank 21 thus places the spring 26 under tension so that there is a tendency at the release of the crank 21 for bringing the seats 18, 19, 20, into registry at 'jected by spring 31 in block 32 which acts as a guide for the ratchet 30' and also pro-- vides housing about the disks 17, 25. With a coin in the seat 18, the ratchet 30 is forced 8'0 29. With the coins or checks in the seats 19, 20, there is thrusting outward respectively of ratchets 33,34, against their respective springs 31. The coins or checks in the respective seats 18, 19, 20, serve as cams in coacting 5 with shoulders or ledges on the ratchets 30, 33, 34, to shift such successively suflicient radial distances to clear the tooth 29. a

In the event any coin be omitted, the 5 ratchet responding thereto would not be retracted and it would not be possible to shift the less than full quota group of coins past the ratchets. Of course absence of coins would also hold the disk 25.1ocked. However, with the coins of the denominations re- 'quired, the holding ratchets 30, 33, 34, are

thrust into retracted position to permit the shifting of the disk 25 and its tooth 29 clear of these ratchets. Pin 35, through cover plate I 36 for the housing, is anchored by screws 37.

may be reset; I

At this position of clearing of these ratchets 30, 33, 34 (Fig. 4), the pin 35 rides in way 38 in the disk 17 to engage the edges of the respective checks. There is thus insured ejection of the coins into chute 39 for reception by box 40 as a casting fast with the housing 36. The housing 36is provided with lid 41 having lock 42 which may be released for obtaining access to the box 40 in removing the coins therefrom. r

i In the instance wherein the disks are shown as having two feed seats for checks and as herein disclosed, the teeth 29 are in dupli- "cate remote from the forward holding ratchet groupings. There is thus a locating of .rearwardholding ratchet 43 (Fig. 5)., This ratchet 43 has minor thrusting spring 44 compressed by plug 45 when door 46 of the device 1 is in closed position. This means that with the cabinet set up, this ratchet 43 is in position: to engage tooth 29 against any rearward travel of. the disk 31. I

Lock 47 carried by the door 46 maintains the housing closed against unauthorized access thereto. With'the door 46 swung to open to be clear of its holding the disk 25 from rearward rotation. When the coins are ejected into the chute 39 the ratchet 43 holds the disk 25 against recover from the initial position. This is a safe-guarding against any tripping attempt for recovering the coins after operation has started. Such course of attack on the machine is rendered ineffective bv' teeth 49; These teeth 49 are controlled by the ratchet 43 when the ratchets 30, 33, 34,

have been released by the coins.

" f The disk 25 has key connection 50 with the shaft 15 which'carries the fixedly mounted sprocket 14.- The coaction between the teeth 29 and the ratchet 43 insures a one-way rotation of the crank 21. However, when the device is to be recharged, an opening of the door 46 allows the spring 44 to clear the ratchet 43 so' that the vending mechanism I To operate the vending machine, place the amount of coin indicated in the proper seat or seatsat the window 16. Operate the crank 21 clockwise against the resistance of spring .26. This efi'ectstransmission through the disk 25 as the checks move in clearing the locked position of this disk from the holding actionof the successive ratchets 30, 33, 34. The continued movement brings about ejection of the coin or coins by the action of pin 35. This operation occurs while the reverse holding ratchet 43. has had the tooth 29 moved'to travel clear therefrom. The disk 17 accordingly has successive travels .of 180 between vending operations. The movement of the disk 25 as effected by the disk17 therewlth causes the disk 25 to operate any desirable vending mechanism to deposit an article of theratchet 30. "-Thus when the machine is empty, the coins, even though of pro er denominations, cannot pass the first ratc et and consequently the operator can not operate the machine nor will his coin be received by the machine.

Adjacent the bottom of the machine 1, chute 56 is provided tobreak thefall of the articles coming-from the vending mechanism and to further direct such toward the opening 4 where theyare easilyfaccessible.v
